.C EMENT-KILN-CLEANING MACHINE.

SPECIFICATION forming part of Letters Patent No. 757,522, dated April19, 1904.

Application filed May 25,1903. Serial no. 158,677. (No model.) i

To a. whom it may concern:

Be it known that I, CHESTER J. VAN DOREN, a citizen of the UnitedStates, residing at Iola, in the county of Allen and State of Kansas,have invented certain new and useful Improvements in Cement KilnCleaning Machines, of which the following is a specification.

My invention relates to a cement-kiln-cleaning machine; and my object isto provide an effective machine whereby the arduous manual laborheretofore required to perform this work is reduced to a minimum.

The two essential features of the invention consist in a rotary head forrotating a cleaning-bar and a carriage for reciprocating saidcleaning-bar. These two elements are connected in such a way that theymay be operated either simultaneously or independently.-

The more important of the minor features resides in a mounting for theframe carrying the rotary head and the carriage, whereby universalmovement is applied to said frame in order that the cleaning-bar may bereadily brought into contact Withfits work.

Although I do not claim any part of a cement-kiln or the arrangement ofkilns in cement-works, the following brief description will assistothers in more thoroughly understanding my'invention. I

In cement-works the kilns, which are cylinders rotatably mounted andabout sixty feet long, are usually arranged in two rows, with a gangwaybetween, varying from fifteen to twenty feet in width. 'In the center ofthis gangway and extending longitudinally therewith I locate a track forthe operation of a truck provided with a platform having universalmovement, upon which I mount my machine in order that it may be readilybrought opposite any of the kilns requiring cleaning. The instrumentinserted in the kiln to remove the incrustation therefrom consists of abar which for convenience in handling is made in sections shorter thanthe kiln, so that as the cleaning operation progresses from the fronttoward the rear of the kiln one or more lengths may be added to completesaid cleaning operation.

Referring now to the drawings, which illusits track in section.

trate my invention, Figure 1 represents a plan view of the machine.elevation of the same in position for opera tion. Fig. 3 is a reducedcontinuation of Fig.

2, showing the cleaning-bar inserted in a kiln.

Fig. 4 is an enlarged vertical section of the frame and the carriageemployed for reciprocating the cleaning-bar. Fig. 5 is an enlarged frontelevation of thecarriage with Fig. 6 is a vertical section of the same,taken on line VI VI of Fig. 5. Fig. 7' is a cross-section of the frontend of the carriage and the cleaning-bar located therein, taken on lineVII VII of Fig. 6. Fig. 8 is a broken front elevation of the machine,showing the revolving head forming one of the essential features of theinvention. Fig. 9 is a vertical section of the revolving head and itsbearing, taken on line IX IX of Fig. 8. Fig. 10 is a detail of anextensionbar adapted to be secured .to the cleaning-bar.

In the drawings, 1 designates a broken longitudinal sectional view ofone of the rotary kilns set on a slight incline and having its interiorlined about one-half its length with fire-brick 2 and provided with anopening 3 in a stationary head 3, through which a cleaning-bar & formingpart of the invention, is inserted. Said cleaning-bar is provided at itsrear portion With a circular groove 5 and a reduced threaded terminal 6for the reception of an extension-bar 7, having a tapering rear end 8and a circular groove 8. 9 designates a track arranged in the gangwaybetween the kilns (not shown) to receive a wheeled truck 10, providedwith a central bearing 11, to which asimilar bearing 12 is Fig. 2 is aside.

pivotally connected at 13 and supports a plat- I the interior of whichflares outwardly at 23 and is provided with slots 24 to receive aloosely-fitting U-bolt 25. The forward portion of the carriage isprovided at its under side with a roller 26, and a pair of eccentriccams 27 27 having integral trunnions 28, are journaled in the frame ofthe carriage above the cams and provided with operating-handles 29.

The lower'portion of the carriage-frame is also provided with a pair ofoppositely-extending eyebolts 30, to which are attached the oppositeends of a cable 31, that passes around two sheave-wheels 32, located inline with the eyebolts and journaled in brackets 33, secured to thefront and rear ends of the machineframe. After passing aroundsheave-wheels 32 the cable is wound around the periphery of a drum 34,rigidly mounted upon a shaft 35, journaled in bearings 35 and providedat one end with a large rigidly-mounted frictionwheel 36, adapted to bedriven in opposite directions by small friction-wheels 37 38, bearings35 being adjustably mounted in the wellknown manner, so they may beshifted by a lever (not shown) in order to throw the largefriction-wheel 36 into contact with either of the small friction-wheels.

Friction-wheel 37 is rigidly mounted upon one end of a transverse shaft40, journaled in bearings 41 and provided at its opposite end with alarge drive-pulley 42, driven by an endless belt 43, connecting it to arigidlymounted pulley 44.

Friction-wheel 38 is rigidly mounted upon one end of a shaft 45,journaled in bearings 46 and provided at its opposite end with a pulley47, which is preferably of smaller size than pulley 42 and. is driven ina reverse direction to thelatter by an endless cross-belt 48, operatingover pulley 44 and beneath belt 43.

' Pulley 44 is rigidly mounted upon a transverse shaft 49, journaled inbearings and provided near its opposite end with a large rigidly-mountedpulley 51, which in turn is driven by a smaller pulley 52 with aconnecting-belt 53. Pulley 52 is mounted upon a shaft 54,driven by asuitable motor (not shown) carried upon platform 55 of the machine.

The rotating head of the machine consists of a cylinder 56, the interiorof which flares outwardly in opposite directions from a central point 57for a purpose hereinafter described. Said cylinder is journaled at thefront end of the machine in bearings 58 and provided with arigidly-mounted centrallydisposed cog-gear 59 and fourdiametricallydisposed rollers 60, the adjacent peripheries of which arearranged to forma hollow square 61 for the reception of thecleaning-bar,which is rectangular in cross-section and loosely fits insaidhollow square, but is rotated with the cylinder by the rollerscontacting with its corners.

Cog-gear 59 is driven by a train of gearing consisting of anintermediate gear 62, a pin- 1on 63, rigidly mounted upon one end of ashaft 64, journaled in bearings 65 and proengagement with the loosepulley by a lever 72 for the purpose of locking said pulley upon theshaftin the well-known manner.

Pulley 7 O is driven by an endless belt 73, operating over a smallpulley 74, rigidly mounted upon shaft 49.

The following is a brief description of one way of operating my machine:The machine is positioned with its rotary head opposite opening 3 in thekiln. The carriage is then run back to the rear, end of its track, andthe rear portion of the cleaning-bar is locked in position on thecarriage by the cams 27 27 and roller 26, while the forward end of thecleaning-bar extends through the rotary head. 7 As the lower portions ofthe cams incline toward each other, it is obvious that'as the car riagemoves forward cam 27 will bind tightly upon the cleaning-bar and causeit to move forward with thecarriage, and when the latter moves towardthe rear end of the machine cam 27 will bind against the cleaning-barand cause it to move back with the carriage. Thus by reciprocating thecarriage the forward portion of the cleaning-bar may be caused to strikesuccessive blows against the incrusta tion on the fire-brick. After themore prominent portions of the incrustations have been thus broken awayvery effective work may be accomplished by rotating the cleaning-bar bymeans of the rotary head .so its square corners will grind away theincrustation. The work is also greatly facilitated at times by impartingboth a reciprocating motion and a rotary motion to the cleaning-bar,which is accomplished by disengaging the cams from the cleaning-bar andsecuring the grooved end of the latter to the slotted head 22 by U-bolt25.

The ease with which the frame can be moved in any direction makes itpossible for the op erator to readily direct the end of the cleaningbaragainst any portion of the incrustation.

After the cleaning operation has progressed as far as the cleaning-barwill reach extension-bar 7 is attached to threaded portion 6 in orderthat the cleaning-bar may complete the removal of the incrustation fromthe fire-brick.

Very good work may also be accomplished by releasing the cleaning-barand its extension from the carriage and running the latter back out ofthe way, so the bar may be grasped and employed as a lever for breakingthe incrustation by using point 57 as a fulcrum.

When it is desired to again secure the cleaning-bar and its extensionupon the carriage, the taperedv end 7 is readily guided between 1 cut,is

the cams 27 27 and the roller 26 by the flaring opening in head 22.

Ido not limit myself to the specific construction shown and described,as the carriage, for instance, might be propelled by a screw, or itcould be made self-propelling by providing it with a motor, which couldbe geared to rollers 21, or the rollers could be dispensed with andrunners substituted therefor, so it would slide upon the track. Therotary head could also be modified and driven by a more simplearrangement of gearing than shown without departing from the spirit andscope of the ap pended claims.

Having thus described my invention, what I claim, and desire to secureby Letters Pat- 1': In a kiln-cleaning machine, a rotary head forrotating the cleaning-bar.
